Jenkins Pipeline gcloud problems in docker

问题

I'm trying to set up jenkins pipeline according to this article but instead use google container registry to push the docker images to.

The Problem: The part which fails me is this jenkinsfile stage block

stage ('Push Docker Image To Container Registry') {
  docker.image('google/cloud-sdk:alpine').inside {
      sh "echo ${env.GOOGLE_AUTH} > gcp-key.json"
      sh 'gcloud auth activate-service-account --key-file ./service-account-creds.json'
  }
}

The Error:

Please verify that you have permissions to write to the parent directory.)

ERROR: (gcloud.components.update) Could not create directory [/.config/gcloud]: Permission denied.

I can't run any command to do with gcloud as the error above is what i get all the time.

I tried create the "/.config" directory manually logged into the aws instance and open up the permission of the folder to everyone but that didn't help either.

I also can't find anywhere how to properly setup google cloud for jenkins pipeline using docker.

Any suggestions are greatly appreciated :)

It looks like it's trying to write data directly into your root file system directory. The .config directory for gcloud would normally be in the following locations for username and/or root user:

/home/yourusername/.config/gcloud
/root/.config/gcloud

It looks like, for some reason, jenkins thinks the parent directory should be in /.

I would try checking where your cloud sdk config directories are on the machine you are running this on (and for the user the scripts runs as):

$ sudo find / -iname "gcloud"

And look for location similars to those printed above.

Could it be that the Cloud SDK is installed in a none standard location on the machine?
